6. John Cena Vs. Alberto Del Rio - United States Championship Match: Raw, December 28, 2015 - 13,538,444 Views

John Cena helped elevate the United States Championship in 2015 with a weekly open challenge that led to classic matches with Cesaro, Sami Zayn, Dean Ambrose, and more.

At Hell in a Cell 2015, though, Cena made his last challenge. Alberto Del Rio returned to WWE in response and cleanly beat him to win the U.S. Title.

In reality, Cena was leaving the company for a couple of months to film the show American Grit, forcing the immediate title change. Del Rio - who was reportedly lured back to WWE with a big-money offer - got the honor.

Unfortunately, he soon ended up flopping in WWE, and his reign as U.S. Champion brought the belt back to its previous level.

When Cena returned, he got his rightful rematch, and it came on Raw. Cena was dominating Del Rio when his League of Nations cohorts, Rusev and Sheamus, ran in for the disqualification.

They beat him down until The Usos made the save, but they also fell victim to the League. Finally, Roman Reigns ran out, backing the heels away.
